Amazing Sleeping Bag!

[This review was collected as part of a promotion.] I recently upgraded my sleep system and I chose the Ascent Down 15 F/ Regular as my sleeping bag. So far, I have taken it on multiple trips through snow and blizzards in both northern California and Colorado and it has performed amazingly. Things I like: - It packs down small, which for me was a big plus over my older, more bulky sleeping bag. The Ascent is small and light which has been a big plus for my backpacking. - The armholes - Waking up in the cold morning and having to get out of a warm sleeping bag has always been a bummer for me. However, with the ascent the snaps and zippers allow you to practically wear the sleeping bag, which has really added a layer of comfort to my mornings when I am out camping. - It's warm. So far it's kept me warm in conditions as low as 20 degrees Fahrenheit. I've really enjoyed snow camping with this bag this season, it's performed great within its rated temperature range. - Quality - The zippers are great and solid, the construction is clean and sturdy. I don't have anything that I don't like about this bag. For colder fall and mild winter/snow camping, this sleeping bag is great. However, I wouldn't push it past its rating. In conclusion, I am over the moon with this purchase and I am excited for the many adventures to come that this bag will accompany me on.

Wow!

[This review was collected as part of a promotion.] I love this bag. It has way more features than any other bag. Being able to stick your feet out the bottom and having zippers on both sides is awesome. I used the bag on a backpack trick and it pack small and was perfect for the season.

Nice Bag

[This review was collected as part of a promotion.] I'm really enjoying this bag. Packs small, and has good zipper placement for venting, sitting up, and even walking around. I tend to sleep on the cold side. I felt comfortable at about 45-50 degree temps. When it dropped below 40, I felt most comfortable with a 50 degree quilt thrown on top.

Go To Bag

[This review was collected as part of a promotion.] Great sleeping bag, perfect size to weight ratio. This is my new "go to" bag.
